All right. Thanks, Amy. Now to another case of turbulence on a flight between passengers. This is the second time in a week a flight was diverted because of a fight over seat space. ABC's David Kerley has this story. Reporter: A hospital room served as a courtroom where frenchman Edmond Alexandre heard the charges of interfering with the crew on a flight from Miami to Paris on Wednesday. He became upset when the seat in front of him was reclined complaining his diabetes made it problematic. The flight attendant tried to calm him but according to the charging documents he became more agitated following him and grabbing his arm that led to the flight mar surveillanceshals breaking their cover. He had a right to complain. He had a right to say, this is hurting me. Reporter: Just days earlier on another flight a woman threw a cup of water in the face of a passenger behind her because he used a pair of these, knee defenders to keep that seat from lee cleaning. Both flights diverted. A rash of unruly passenger incidents. It's not your imagination. Seats are actually getting smaller on planes today. Airlines are trying to pack in more passengers in order to be more profitable. Reporter: What's different in Wednesday's incident federal air marshals jumped into action. Their job is to stop a terrorist threat. I got a firsthand look donning protective gear for a simulated attack but a terrorist is different than an unruly passenger. Those federal air marshals are trained, their call whether they break their cover. They felt the flight attendant was threatened so they interve intervened. We don't hear that very often. Live in Washington, the pictures are incredible. Thank you.
